The Xen heap is 12MB on i386 and 16MB on x86/64. So allocating a few kilobytes is no problem.

Hi,
I am trying to add some extra data structures in the hypervisor for my research. I hear that the Xen hypervisor space is very limited and I need to be careful adding large structures. Can someone give me an idea of big it is and how much headroom I have? I would like to create a structure of say 3000 (minimum) to 24000 bytes.
Thanks
